Refractive errors are the leading cause of preventable visual impairment, to which web-based remote refraction could contribute. We report real-world 2021-2022 data of the underlying algorithm and validated these to conventional prescriptions among healthy individuals (high visual acuity and satisfactied current refraction). Participants were 18-45 years with a spherical (S) error between -3.50 + 2.00S to -2.00 Diopter Cylinder (DC), reported as Spherical Equivalent (SEQ) in mean differences and 95% Limits of agreement. Consecutive measurements (n = 14,680) were assessed of which n = 6386 selected for validation. The mean difference was 0.01D(SD 0.69) and -0.73D(SD 0.92) for myopes and hyperopes respectively. This algorithm shows variation, nonetheless, 67% and 82% of myopes were within ±0.5 and ±0.75D. The test underestimates hyperopes (34% and 50% within ±0.5D and ±0.75D) and had inconsistencies distinguishing hyperopia. This proof-of-concept shows home testing has the potency to increase accessibility to care by delivering a valuable alternative for uncomplicated refractive assessments.
屈光不正 是可预防视力损害的主要原因，基于网络的远程验光可能有助于解决这一问题。我们报告了2021 - 2022年基础算法的实际数据，并在健康个体（高视力和满意的当前屈光状态）中将这些数据与传统验光处方进行了验证。参与者年龄在18 - 45岁之间，球镜（S）误差在-3.50 + 2.00S至-2.00屈光度柱镜（DC）之间，以球镜等效值（SEQ）报告平均差异和95%一致性界限。对连续测量值（n = 14,680）进行了评估，其中n = 6386个被选用于验证。近视者和远视者的平均差异分别为0.01D（标准差0.69）和-0.73D（标准差0.92）。尽管该算法存在差异，但67%的近视者和82%的近视者在±0.5D和±0.75D范围内。该测试低估了远视者（分别有34%和50%在±0.5D和±0.75D范围内），并且在区分远视方面存在不一致性。这一概念验证表明，家庭测试有潜力通过为简单的屈光评估提供有价值的替代方案来增加获得医疗服务的机会。
